1. The design Each edge of the wireframe DNA origami tetrahedron is composed of four dsDNA helix ~90 nm long and is connected to the other two neighboring edges at the vertices by flexible joints. The scaffold strand, coming out from the struts, crosses each vertices twice. The connection points between the struts are composed by 5 bases left at single strand. The number of bases composing three of the six struts slightly differ to fold completely the scaffold strand. Three of the struts have been designed with a central seam which separates the two half of the pillar itself, so we properly prolonged the staples strands tuning their pairing to build a cage around the seam in order to reinforce the central part. In the three pillars left, the scaffold strand still forms a central seam but the external helix extends along the entire length of the pillar maintaining the struts more robust (Fig. S1).
Figure S1 Visual model of the scaffold strand folding path: six 4-helix bundles in blue, the flexible connections at the vertices in red. There are two different types of struts: the two half struts typology and the strut with a central seam. On the right side, a focus of the vertex connection.

Two different sets of staples fold the two struts involved in the probe-target actuation facet: (i) staples pair the entire scaffold strand of the struts (0ss), (ii) staples leave unpaired 4 nucleotides of three helices of the struts (3ss) (Fig. S2). The purpose was to plan two different tetrahedral DNA origami characterized by different mechanical properties.
Figure S2 Two set of staples containing: no single strand (0ss) and 4-single strands bases in 3 helices (3ss). The scaffold strand is blue, the structural staples strands are red, the staples involved in the variable part of the struts are grey, and the green dotted segments are the 4-bases gaps where the scaffold strand is left unpaired. On the right, the arrows indicate the position and the number of weak points.
0ss and 3ss have been separately designed through the help of design-assisted software caDNAno; the list of nucleotide sequences of staple strands, catchers strands, probe and target are shown in section 7.
2. Purification and additional characterization The purification of the folded structure from excess of staples strands has been initially operated through Amicon filtration. In Figure S3(a) is shown an UV image of agarose gel: in the first and in the third lanes we can observe the migration of the ladder and of the M13mp18 while the forth and the fifth wells were filled with DNA origami tetrahedron respectively before and after the Amicon purification. The red box in Figure S3(a) identifies the gel bands corresponding to the well folded origami. As expected, after the purification step the staples were removed and the origami concentration was increased (band brightness enhancement). Meanwhile we witnessed to the formation of two slower bands which correspond to larger constructs, probably derived from the aggregation of two and three tetrahedrons. SEM characterization confirmed the agarose gel indications: most of the tetrahedrons analyzed were aggregated (Fig. S3(b),(c)) or broken in different places, probably because of the harsh purification step. These results suggested that the purification of the DNA origami tetrahedron with Amicon was not successful; for this reason no staple purification has been used in all the performed experiments.
The DNA origami concentration was calculated using ImageJ software: the brightness of the whole lane can be assumed proportional to the M13mp18 initial concentration (10 nM), so the ratio between the brightness of the origami band and of the entire lane is equivalent to the ratio between the concentration of the scaffold strand and of the origami tetrahedron. SEM analysis did not highlight structural differences among 0ss and 3ss tetrahedrons.
Figure S3 (a) Agarose gel electrophoresis of DNA origami tetrahedron shows the concentration and the aggregation enhancement after Amicon purification, M13mp18 is used as a control of the folding success; (b) and (c) SEM pictures in which there are well-folded tetrahedron, broken and aggregated DNA architectures.

The anchoring of AuNP to the DNA origami was extrapolated from agarose gel analysis: first we calculated the DNA origami concentration from the fluorescence intensity of well folded DNA origami band compared to the intensity of the entire lane as described above. Since the total amount of M13 in the sample was 6.25 nM and we loaded 10 μl in each well of the gel we can estimate the concentration of well folded DNA origami present in the bands of interest. In the same way we calculated the AuNP absorbance and we obtained the ratio between the absorbance in the band of interest and the entire lane. Since the initial concentration of AuNP was 6.25 nM, the ratio AuNP: M13 is 1:1 while the ratio AuNP: well folded DNA origami tetrahedron is 4:1. Since the band of interest may contain tetrahedron without AuNP, tetrahedrons with only one AuNP, and tetrahedron correctly formed with 2 AuNP, we further needed to evaluate the relative probability of these three configurations. We analyzed 220 DNA origami from 50 SEM pictures and we found out 115 structures with AuNP dimers, 105 structures with a single AuNP: therefore, we assumed a ratio between dimer and single NP of 1:1.
Finally, from the gel presented in Figure 1 the yield of dimers obtained was (1) 13% for 0ss, (2) 8.3% for 0ss+Target, (3) 10% for 3ss and (4) 10% for 3ss+Target.
3. AFM analysis of the kite-like DNA origami AFM analysis was performed in contact mode in air [S1, S2], on the “kite-like” DNA origami and we observed that that almost all the structures were in the flat configuration, except few of them which were folded on themselves (Fig. S4(a)), probably because the scaffold strand can still pull the two halves of the broken strut together. Moreover, the flexibility of the vertices provides enough degrees of freedom to allow the folding of the structure on itself even if it is statistically less probable, due to the electrostatic repulsion between the origami struts. The profile of the kite-like DNA origami deposited on mica as measured from the topographic images, post-processed with Gwyddion software, highlights an average strut height of 2 nm which is substantially lower than 2 double-helix value in solution (between 4 and 5 nm) (Fig. S4(b),(d))[S3]. Numerically the same results were obtained also in tapping mode in liquid but with a lower image quality. These discrepancies are often observed when imaging in air with AFM because of a combination effects of water drying and AFM tip pressure, therefore these measurements are usually considered only indicative [S4]. The apparent width of the dsDNA molecules is strictly correlated with the tip used, but it was always exceeding the 2 dsDNA diameter in solution, which is to be expected for tips with apex radii exceeding substantially the molecular diameter (Fig. S4(c)).

4. Additional SEM and TEM and Cryo-EM characterization Transmission electron (TEM) and cryo-electron microscope (cryo-EM) have been used in combination with scanning electron microscope (Fig. 1(d)) to validate the folding of the tetrahedron (Fig. S7).

Figure S5 TEM images representing the well-folded tetrahedron shown in Figure 1(d) (scale bar 50 nm).
Figure S6 DNA origami tetrahedron conjugated with one AuNP: on the left SEM image with a broken tetrahedron in which is visible the right AuNP positioning; on the right cryo-EM of a broken tetra with one AuNP confirmed the central positioning of the AuNP in one AuNP facet.
In order to selectively decorate the DNA origami structure with one or two gold nanoparticles, we initially synthesized it using only one set of catchers strand which are involved in the binding of one AuNP.
The conjugation of one AuNP to the DNA tetrahedron, still allows to visualize the tetrahedral shape. Moreover, the presence of kite-like structure, as in Figure S6, evidences the precise positioning of the AuNP in the center of a tetrahedral facet.
Further functionalization with the second gold nanoparticles has been performed through the addition in the DNA origami synthesis mix of another set of catcher strands, recognizing the same AuNP functionalization. The presence of a second NP attached to the tetrahedral architecture, further increases the signal background, coming from secondary electrons scattered by the two nanoparticles, thus outshining the signal generated by the origami itself. In some cases, the triangular shadow, attributable to DNA origami, can be still observed (Fig. S7).
Figure S7 Dimers of gold nanoparticles with a triangular like shadow representing DNA origami tetrahedron with two gold nanoparticles (Scale bar 100 nm).
Cryo-EM characterization (Fig. S8) showed triangular like structures heterogeneously distributed in the grid, often anchored to the lacey carbon film formed net. Nonetheless, it is still possible to appreciate the presence of many AuNP dimers deriving from tetrahedrons not clearly distinguishable.

5. SAXS data In order to facilitate the comparison between the SAXS pattern before and after the structure factor derivation in Figure S9 is shown the zoom of the data presented in Figure 2(a) and (b) restricted to the q-range of interest.
Figure S9 Zoom in the q-range of interest of SAXS data presented in Figure 2(a) and (b)in the main text. (a) Scattering pattern of all samples and the DNA- functionalized AuNP reference sample do not present significant peaks in the region of interest since the signal is mainly dominated by free AuNP in solution; (b) to extract the particle-particle interference, the structure factor has been derived by dividing the pattern with the AuNP signal (gold-yellow line). The structure factor of the different tetrahedrons highlights the presence of differences only between 3ss before and after target hybridization while no relevant variability has been recorded in 0ss structures after target addition.
6. LSPR analysis A basic equation to calculate the actual extinction spectra is:
A + S + R + T = 1 (1) where A is absorption, S is scattering, R is reflection and T is transmission of the light and A+S= E represents the extinction. Neglecting the difference in the light reflection from the surface of clean gel and the one with AuNP, E = 1- T. Thus, the final equation to calculate the extinction is:
E = (I0-Ii)/(I0-Ibg) (2) where Ii is the corresponding intensity of light passed through each band, and I0 is the intensity of light passed through the clean gel in a position without origami and nanoparticles. Ibg is a dark thermal noise of CCD. At least 5 different positions along each band have been characterized and finally averaged [S5].
6.1 LSPR measurements in liquid
The measurements in liquid have been performed in a home-made cell fabricated from a PMMA slab with two coverslip glasses attached to both sides. 10 μl of liquid sample was loaded in the chamber preliminary created in the slab avoiding the formation of air bubbles.

Figure S10 Extinction spectra of AuNP-tetrahedral DNA origami in solution before and after the probe-target actuation of 0ss and 3ss respectively demonstrating that LSPR shift cannot be observed. In both samples the target addition does not shift the plasmon resonance for the contribution of free AuNP dominating the spectra, as discussed in the main text. However, we observed that in both cases after the target addition the resonance width decreases, as a consequence of the greater stability conferred to the structure by the hybridized probe, and the subsequent reduction of thermal fluctuations.
6.2 LSPR measurements in gel and data treatment
The extinction spectra show a peak in the range of 525-535 nm which is attributed to the LSPR in single gold AuNP or dimers. The spectra in gel demonstrate a different extinction at short wavelengths complicating an estimation of LSPR position. Since the gel density, gel hydration and AuNP size in each series of experiments are supposed to be constant the difference in the extinction is caused by a variable gel thickness of the lanes.
The best agreement between the experimental data for single DNA-coated AuNP in liquid and simulations was obtained with εeff = 2.0 which in terms of effective medium approximation (EMA) corresponds to εeff = 0.34∙εDNA + 0.66∙εwater, where εDNA = 2.450 and εwater = 1.769 are dielectric permittivity of DNA and water respectively. The εeff in gel increases by 1% since dielectric permittivity of gel is higher than of water (εgel = 1.796). The experimental data displayed in Figure 3(c) were fitted with 2 Gaussian curves (Fig. S11), each of them represents the particular extinction process and is related to: i) plasmon excitation in AuNP dimer, ii) variation in gel thickness and/or structure. The first term was fully variable while the wavelength position and the peak width of the second were fixed and obtained from the measurements of clean gel (Fig. S12). Notice that the peak height was variable in the second case.
Figure S11 it procedure. The experimental data of 3ss-AuNP hybrid structure without and with target displayed in Figure 3(c) were fitted with 2 Gaussian curves, each of them represents the particular extinction process and is related to: plasmon excitation in AuNP dimer (green curve), variation in gel thickness (red curve).
Figure S12 The image below represents a fit of the gel spectrum with one Gaussian function. Its peak position will be fixed at 475 nm, a width at 160 nm, while a height will be variable.
